Evaluation of psychological therapies for schizophrenia
- evidence for effectiveness
  - Jauhar et al reviews 34 studies of CBT and found CBT has a small but significant effect in positive and negative symptoms
    - McMonagle and Sultana
      - found only 3 studies in which participants were randomly allocated. None yielded useful information about behaviour change
  - Pharoah et al
- Treatments improve quality of life but don't cure
  - CBT allows patients to make sense of and challenge symptoms
  - Family therapy helps reduce the stress of living with a sufferer
  - Token economies help make patients' behaviour more socially acceptable
  - failure to cure is a weakness of these treatments
- Ethical issues
  - no serious side effects
  - CBT involves challenging thoughts, may be political
    - these are wweknesses
- evaluation extra
  - studies are too pessimistic and don't involve control groups
  - art therapy also effective but not offered to many patients
family therapy reduces hospital readmission rates and improves quality of life
- results of studies are inconsistent so evidence is weak
- Pharoah et al
